TEXT1="some-text a.b.c.d a.b.c.d a.b.c.d a.b.c.d" TEXT2="some-text 1.1.1.1 2.2.2.2 3.3.3.3 4.4.4.4" sed -i "s/$TEXT1/$TEXT2/g" $INFILE ;a.b.c.d are unknown IP Addresses. ---------------------- I have tried this: TEXT2="some-text 1.1.1.1 2.2.2.2 3.3.3.3 4.4.4.4" IP_REGEX="\b(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][$ TEXT1="^some-text[ \t]${IP_REGEX}[ \t]${IP_REGEX}[ \t]${IP_REGEX}[ \t]${IP_REGEX}" sed -i "s/$TEXT1/$TEXT2/g" $INFILE ---------------------- What I have does not work, and I need some assistance. Your help is appreciated. Thanks. -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
